I use the 24-hour clock on my wristwatch and all my clocks ... now do you, as a Perl programmer, know off the top of your head how many seconds are in 12 hours? Probably not, because it is a useless unit! But I bet you knew 86400 seconds in a day :-)

As for leap seconds; ugh. 

perl -MDateTime -E'
say DateTime->new(time_zone=>"UTC",year=>1972,month=>12,day=>31,hour=>
+23,minute=>59,second=>60)->add(months=>$_)->month_name for (0,1);
'
December
February

... we escaped this year because July is longer than June (hmm, I wonder if that's why they moved it to June?): 
perl -MDateTime -E'
say DateTime->new(time_zone=>"UTC",year=>2015,month=>6,day=>30,hour=>2
+3,minute=>59,second=>60)->add(months=>$_)->month_name for (0,1);
'
June
July

The way forward always starts with a minimal test.
